add custom title after page break

i am using docx4j library and using templating to genearte report from my application.
i have following requirement,
When a page break comes between a paragraph content, i need to add a custom title before the next page content starts as you see in figure.
I know if we need to repeat same title , we can achieve it by using table and repeating header row. But there title will be same. Here I need custom title.
Paragraph is getting populatated from backend and how do we figure out page breaks happens at code level ?
Thanks in advance

This has to do with the Word Object Model. Word really does not have the concept of pages in the underlying structure of a document. Word Doesn't Know What a Page Is by Daiya Mitchell, MVP
Because of that, this would be better posted in the Word Answers forum hosted by Microsoft.
There are ways to deal with this using headers (not table headers necessarily although they can be used) or using a shape anchored to the table to occlude the word "continued" in the original header.
When you say templating, are you talking about Word templates (term of art) or something else?

HTML/CSS shapes with docx4j

I am using the docx4j in a java app which parses HTML/CSS and exports a docx.
What I need is to make something like:
but seems like I can only make a couple of tables with docx4j. Can it read entire html css files or only basic html with no css?
Also I've been trying to use everything from flexbox, to display table, to just float ( like 15 years ago ), for making the gird layout.
I am curious if it is a dead end or it's just me and I don't know how to use it

docx4j-ImportXHTML can read CSS.
It uses Flying Saucer to parse the XHTML: https://github.com/flyingsaucerproject/flyingsaucer
Flying Saucer uses CSS 2.1.
If you hit a limitation, the first thing to do is to see whether Flying Saucer has captured the relevant value. If it has, then docx4j-ImportXHTML needs to handle it correctly.
Alternatively, Google to check whether FS handles flexbox etc. I don't think ImportXHTML handles float right now. You could add that, of course.

Bullets not showing in JTextPane

I am developing an editor in Java in which I want to include bullets of different types. I am using HtmlEditorKit. I wanted to add a style sheet but it is not working, I wanted to know if following Pseudo element is supported in Java, if it is supported can you please guide me where I am going wrong?
styleSheet.addRule("ul{list-style-type:none;margin:0px 20px;}");
styleSheet.addRule("li:before{content: \"&#10020\";}");

The Java HTML rendering engine only supports a (very) limited amount of CSS.

Expandable list in pdf files

Can i create an expandable list in pdf files. Expandable list will be of the form :
+Item1
+Item2
-Item3
-Subitem3.1
-Subitem3.2
+Item4
-Item5
-Subitem5.1
-Subitem5.2
-Subitem5.3
Also I need to create the pdf file from Java(I was thinking of using iText, is another library better/easier?). Is this possible. Or is a report in some other standard format(not pdf or html) an easier way out.

First this: I'm the creator of iText, so forgive me for not pointing you to other solutions ;-)
Now for your question: you're asking for dynamic functionality (a tree structure that opens/closes upon user interaction) inside a PDF document.
The most obvious answer is: this isn't possible. When creating PDF, think of paper. Can you print a tree structure on paper that opens/closes when the end user touches the paper? No, you can't, therefore you're asking something that isn't possible in PDF.
The less obvious answer is: it depends. What type of PDF are we talking about?
If you're talking about an interactive XFA form, then you may be able to achieve what you want. The XML Forms Architecture (XFA) is an XML specification that can be used to define interactive forms. When you use XFA, the PDF is nothing more than a container for XML. This XML is rendered dynamically inside Adobe Reader. How to create an XFA form? I only know about two products: Adobe LiveCycle Designer and Avoka Smart Forms Designer.
If you're talking about 'regular PDF', then one option is to embed a swf file. In this case, the tree structure will be rendered by Flash player (which could be a disadvantage, because this might not work with all PDF viewers). Another disadvantage: the tree structure will be confined to a fixed rectangle on a fixed page.
Finally: you can have create such a structure in the bookmarks panel. In PDF terminology, those bookmarks are called Outlines. Obviously, the tree structure won't be a part of the printable content. It will be visible in a separate panel in your PDF viewer.

PDF find out if text is underlined or a table cell

I have been playing around with PdfBox and PDFTextStripperByArea method.
I was able to extract information if the text is bold or italic, but I'm unable to get the underline information.
As far as I understand it in PDF, underline is done by drawing lines. So in theory I should be able to get some sort of information about lines somewhere around the text. Giving this information I could then find out if either text is underlined or in a table.
Here is my code so far:
List<TextPosition> textPos = charactersByArticle.get(index);
for (TextPosition t : textPos)
{
if (t.getFont().getFontDescriptor() != null)
{
if (t.getFont().getFontDescriptor().getFontWeight() > BOLD_WEIGHT ||
t.getFont().getFontDescriptor().isForceBold())
{
isBold = true;
}
if (t.getFont().getFontDescriptor().isItalic())
{
isItalic = true;
}
}
}
I have tried to play around the PDGraphicsState object which is processed in the processEncodedText method in PDFStreamEngine class but no information of lines found there.
Any suggestions where this information could be retrieved from ?

Here is what I have found out so far:
PDFBox uses a resource file to bound PDF operators/instructions to certain classes which then process the information.
If we take a look at the PDFTextStripper.properties resource file under:
pdfbox\src\main\resources\org\apache\pdfbox\resources\
we can see that for instance the BT operator is bound to the
org.apache.pdfbox.util.operator.BeginText class and so on.
The PDFTextStripper under
pdfbox\src\main\java\org\apache\pdfbox\util\
takes this into account and utilizes the processing of the PDF with this classes.
BUT all graphical objects are ignored, therefore no information of underline or table structure!
Now if we take a look at the PageDrawer.properties resource file we can see that this one bounds to almost all operators available. Which is utilized by PageDrawer class under
pdfbox\src\main\java\org\apache\pdfbox\pdfviewer\
The "trick" is now to find out which graphical operators are those who represent underline and tables and to use them in combination with PDFTextStripper.
Now this would mean reading the PDF file specification, which is currently way to much work.
If someone knows which operators are responsible for which actions to draw underlines and table lines please let me know.

As you mention -- PDFBox uses resource files, to bind PDF operators/ instructions to visitors which will process the information.
You'd probably best start by copying PDFBox's existing visitor into your own source-folder, and then adding/ extending the implementation from there.
My long-ago PostScript experience recalls 'moveto' and 'lineto' operators. Since PDF is roughly PS-based, you'll be looking for something similar.

PDF format is a b*tch -- it's HTML, done wrong. It represents graphical implementation, not semantics. Even reconstructing sentences is difficult -- words or even individual characters are positioned, the 'space' or 'newline' must be algorithmically reconstructed. In short, Adobe are a*holes. And Reader is an non-ergonomic, bug-riddled, insecure, bloated pig.
However, you can accomplish your requirement -- if you are willing to put, say, 12+ hours of work in. As well as detecting by position, underlines will typically be emitted in the PDF immediately after their text.. so you can latch your detection by PDF document-order, not just page position.
Also, try constructing a trivial two-line PDF with underlined text. Then see what you can make of it, parsing it back in! The underline should stick out like dog's bananas, and once you can detect that, you'll be well on the way.
PDFBox is not very good for extensibility, it's mainly just a big pile of algorithms. For this reason, just copy the PDFTextStripper source (and maybe have PageDrawer for reference) and prototype from there.
Hope this helps!

you can use Itext to generate pdf reports.
by using itext you can able to put the lines in easy way.
try the follwing.
document.add(new LineSeparator(0.5f, 50, null, 0, 198));
the above code is used to generate lines in pdf report. and set the dimensions according to your choice.
hope this will help you.

As far as I have understood the pdfbox, there is no option by which you can read underline. Maybe you can try itextpdf for this purpose.

According to the api getfont() returns The font size.
You can use getStyle() method and it will return STYLE_UNDERLINE for underlined font. Thus you can retrieve underline style.
